I have applied for a national patent and then I applied for a PCT claiming priority over the national patent and then I applied for a second national patent with improved content over the PCT just few days before the PCT was published. Now, I want to abandon the PCT and patent the content of the second national application which has improved/added matter over the PCT. Is that possible? I wonder if I can cancel the PCT and claim priority over the second national patent or cancel the PCT and claim priority over the PCT. I do not want to have to prove that my improved/added matter is novel and inventive over the PCT. Please note I am interested to get US and EU patents.
